IMPROVEMENT IN FLOWS.

To all 'whom it may concern.-

Be it known that I, HENRY S. UHICHESTER, ot' the town of Brunswick, in the county of Rensselaer and State ot New York, have invented a certain new and Improved Changeable Double Plow; and I doliereby declare that the following is a full and exact description thereof, reference being had to the annexed two sheets of drawings, which makela part of this specitlcation, and in which the same letters of p reference indicate like parts in all the figures.

similar left-hand plow, each having a share, a,

mold-board `b, landside c, draft-beam d, and

handle e, all constructed and arranged and secured together, so that each of the plows AB is a complete implement in itself without the other, and capable of being used alone in plowing land and turning or marking separate furrows, the same as any single moldboard plow in common use.

My improved double plow consists ot' the two right and left plows A B, constructed as above described, and united together, but at a distance apart, with both the mold-boards b b arranged on the in ner side and opposite to each other by means oftwo distinct bars, G and D, crossed and pivoted together at their crossingpoint-j', and fastened, at places in the bars on opposite sides of and substantially equidistant from the pivot f, to the forward and rear parts of the plow-beamsd dby means of or by equivalent devices for the screw-bolts g g g g, extended throughholes inthe crossed bars and slots or bar z nor evener E or E on the plows, but to hitch the whiftletrees F F directlyto the clevis or draw-rnd y on each plow A B, substantially as indicated at F/ in Figs. l and 2, and then cross the inside traces ot' the draft-.animals to equalize the dralt on the, plows A and B.

In my improved double plow it is essential tha the crossed bars C D should be pivoted together at their crossing-pointf, so as tothereby maintain the requisite parallelism and opposite positions of the" plows A B under all circumstances; and in my improved double plow, composed ot' the two complete right and left plows A B and the pivoted crossed bars CVD, constructedand arranged and-secured together as hereinbefore described,theforward inwardly-inclined sides 'i ijj of the holding-bars G I) themselves serve to collect together the spread- V`mold-bard b of either plow in respect to its beam d, so that my improved doubleplow may at all times be changed into two efficient single plows by merely taking off the parts by which the-beams of the plows are fastened t0` each other. y f

Fig. 3 is a plan ot' a double plow for simultaneously turning two separate t'nrrows ontward instead of inward; and my improved double plow shown in Fig. l may be changed into a double'plow like that shown in Fig. 3 by simply'putting and securing each of the right and left plows A B in the place of the other; and when my improved double plow shown in Fig. l is changed into one like that shown in Fig. 3 it may then be converted into a potato-digger, such as is shown in plan by Fig. 5 on Sheet Il and in sectional elevation in Fig. 6, by securing a scooping perforated platform and apron, G H, Fig. 7, between and` to the plows A B by means of an axis, k, and adjustable hangers 1 I, in the manner shown by thosedrawings; and myimproved donbleplow shown in Fig. l may he changed into adonblemold-board plow, such asis shown in plan by i Fig. 4, by simplyreinoving' the crossed bars G D and the banzlwhen used, and then fastening-the plows A-B Vtoge't',her,flii'dsideto.landwith the two shares opposite toeach other and cpable of being set-at various distances apart,

and so as to simultaneously turn two separate furrows either` both inward or both outward, and that a potato-digging scoop has been arranged and secured in an inclined positionbe tween` and 'to two right and left shares 5 and I believe chata double mold-hoard plow has been heretoforenso constructed' that it could also be used esasinglemold-board plow, and thntcross braces have been arrenged'in combination `with `two beams and movable shares in the construction of cultivritors; and I do not claim any ci those features; but I ldo not know or believe that any implement has ever before been composed of two complete righta'nd left plows, A' B, and two crossedbars,G D, pivoted together et their crossing-point. j', end ellconstructed' l and arranged and secured together es hereinbefore described,'and shown by Figs.y l and 2 otheennexed drawings, so as to be capable of all the alterations hereinbefore specified as apperteining` to my improved changeable double' plow.

What I claim as new andof and desire to secure by Letters letent, is

The combination andarrengement of the crossed bars C and D,pivoted ltogether at their crossing-pointf, with the-right and. left plows A and' B, so ns to constitutean implement for simultaneously hilling up both sides .oa row of corn, as herein described, the same being j capable of alteration into two separate vsingle v moldboard plows, ora double mold-board plow, or e plow for simultaneousl y turning two seperate fnrrows ontward,or a potatodigging'plow,.

asherein set forth. Y HENRY S. OHICHESTER.
